Is there a tool or method to determine IP blocks assigned to an organization by ASN? I.e. if I have an organization's ASN number I want to know all blocks assigned to that ASN.

I use the excellent tool: http://bgp.he.net/ and select the "Prefixes V4" tab after entering the ASN in the webform. -Hank

Thank you.
